Is there a fuse I can pull to cut power to my radio only? The reason I ask is because I put an aftermarket double din headunit in my 09 Taco but it cant be turned off. The only way to turn off the radio is to pull the key out of the ignition (per Pioneer). The headunit interferes with my CB radio (for some odd reason) and will not allow me to transmit clearly.

Instead of pulling a fuse, simply place a switch inline to the red wire feeding the acc. lead to the radio.

Hops that helps. There really shouldnt be any reason for it to effect your CB though. I would recheck your grounds on the CB personally.

good idea. Will have to try that. I dont know why it effects it but it does. When I depress the talk button to transmit the CB transmits some crappy noise to everyone else, and the music gets distorted on my speakers. This all started once I had this new radio put in too.
